The Wilhelms and the Firestones spend an evening with Sandor and his date Olivia at a Christmas party at the club. Before and on the way the party Mary shows Arthur how she is becoming a new woman. Throughout the evening during dances with the various partners spirited, flirting conversations alluding to sex take place. At the table "under the tablecloth" actions take place. Towards the end of the party our group notices a group leaving early. They are agreed that this party may be a group of swingers.
